Fixes 236695

Refactored Sparkle's unarchiving system into SUUnarchiver, a factory for SUPipedUnarchiver and SUDiskImageUnarchiver. I removed that nasty cleanUp call by now copying out the contents of the DMG into the /tmp directory and unmounting. Nice!

This changed a fair amount so please test with your build and let me know if it explodes things. Works in my tests, though.
